Integrating Keplars with PocketBase for Production-Ready Email Workflows

PocketBase has quickly become one of the most loved backend solutions for developers building lightweight SaaS products, internal tools, MVPs, and modern applications.

It gives you:

• Authentication
• Database
• Realtime APIs
• File storage
• Admin dashboard

…all in a single executable.

But once your app starts growing, email infrastructure becomes painful surprisingly fast.

You suddenly need:

• transactional emails
• onboarding flows
• OTP/password reset emails
• marketing campaigns
• tracking
• automations
• domain management
• analytics
• scalable delivery

Most developers end up stitching together SMTP providers, templates, tracking systems, and automation tools separately.

That's exactly why we built the official PocketBase integration for Keplars.

In this guide, we'll walk through how to integrate PocketBase with Keplars to build scalable email workflows with minimal setup.

What is Keplars?

Keplars is a developer-first email infrastructure platform designed to simplify:

• transactional emails
• marketing emails
• automations
• real-time tracking
• OAuth sending
• custom domains
• email APIs
• SDK integrations

The goal is simple: reduce infrastructure friction so developers can focus more on building products instead of maintaining email systems.

Why Use Keplars with PocketBase?

PocketBase is extremely lightweight and developer-friendly.

Keplars complements that philosophy by making communication infrastructure equally simple.

Together, you get:

• Transactional emails
• Marketing campaigns
• Real-time email tracking
• Automations
• OAuth-based sending
• Custom domains
• Sandbox email testing
• Webhooks
• SDKs across 11 languages

Architecture Overview:

Here's the typical flow:

1PocketBase App
2      ↓
3Business Logic / Hooks
4      ↓
5Keplars Email API
6      ↓
7Email Delivery + Tracking + Automations
8      ↓
9Webhook Events → PocketBase

Step 1: Create a Keplars Account

Start by creating an account at keplars.com.

Once logged in:

1. Create a project

2. Generate an API key

3. Configure your sender/domain

4. Enable tracking

Step 2: Install PocketBase

If you don't already have PocketBase running:

1# Download PocketBase
2https://pocketbase.io/docs/
3
4# Run PocketBase
5./pocketbase serve

PocketBase will start locally at `http://127.0.0.1:8090`.

Step 3: Install Keplars SDK

Example using Node.js:

1npm install keplars

Step 4: Configure Environment Variables

Create a `.env` file:

1KEPLARS_API_KEY=your_api_key
2[email protected]

Step 5: Send Your First Email

Example using the Keplars SDK:

1import { Keplars } from "keplars";
2
3const keplars = new Keplars({
4  apiKey: process.env.KEPLARS_API_KEY,
5});
6
7await keplars.emails.send({
8  from: process.env.KEPLARS_FROM_EMAIL,
9  to: "[email protected]",
10  subject: "Welcome to PocketBase",
11  html: `
12    <h1>Welcome!</h1>
13    <p>Your account has been created successfully.</p>
14  `,
15});

That's it. You now have email sending, delivery handling, tracking, and analytics running on top of your PocketBase app.

Step 6: Add Email Tracking

Keplars supports sent, delivered, open, and click tracking.

Example response:

1{
2  "id": "email_123",
3  "status": "sent",
4  "tracking": true
5}

This allows you to build user engagement analytics, onboarding metrics, and email performance dashboards directly into your PocketBase application.

Step 7: Build Automations

Keplars Automations allow you to create onboarding sequences, drip campaigns, inactivity reminders, OTP workflows, welcome emails, and follow-up emails.

Step 8: Use PocketBase Hooks

PocketBase hooks make email workflows extremely clean.

Example:

1onRecordAfterCreateSuccess((e) => {
2  // Send onboarding email
3});

You can trigger welcome emails, verification emails, alerts, reports, and notifications automatically after database events.

Step 9: Configure Webhooks

Keplars supports webhooks for delivered events, opened events, bounced emails, clicked links, and failures. This makes it easy to sync communication data back into PocketBase.

Example:

1{
2  "event": "email.opened",
3  "emailId": "123"
4}

Step 10: Add Sandbox Testing

Testing emails safely during development is critical.

Keplars Sandbox Mode helps you validate templates, test flows, debug automations, and preview email events without accidentally emailing real users.

Real Use Cases:

Here are some common PocketBase + Keplars workflows:

SaaS Applications:

• onboarding flows
• billing reminders
• trial expiry emails

Internal Tools:

• alerts
• approval workflows
• notifications

AI Applications:

• AI-generated reports
• summaries
• asynchronous workflows

E-commerce Apps:

• order confirmations
• abandoned cart emails
• shipping notifications

Why Developers Like This Stack:

PocketBase gives developers a fast backend. Keplars gives developers scalable communication infrastructure.

Together: setup stays lightweight, integrations stay simple, workflows stay scalable — without managing multiple disconnected tools.

Final Thoughts:

The goal behind this integration was simple: make production-grade email infrastructure feel as developer-friendly as PocketBase itself.

We're excited to see what developers build with this stack.
